Storyline Narrative 7.3.2

Standard 7.3.2: Develop and use a model to describe the function of a cell in living systems and the way parts of cells contribute to cell function. Emphasize the cell as a system, including the interrelating roles of the nucleus, chloroplasts, mitochondria, cell membrane, and cell wall.

Student Friendly Objective: I can develop a model to show the parts of a cell system and how they help the cell perform its functions.

Anchor Phenomenon: A single cell can be a living organism.  

Big Idea: Cells are systems that complete the functions necessary for life.

Students have been introduced to living and nonliving things, and will now investigate the roles that cells and their organelles play in the survival of an organism. In episode 1, students will engage in brainstorming what functions living things need to perform in order to survive. They may understand that a rock is nonliving and a tree is living, but they will determine what that tree needs to do in order to survive.

 

In episode 2, Students will explore the different parts of a cell and how those parts help the cell perform life functions.

 

In episode 3, students will also learn specifically about the function of the cell membrane through exploring the process of osmosis. They will conduct a lab investigating what happens to a cell membrane, in this case the membrane of an egg, when it is put in different conditions.

 

Students will take their newfound knowledge and explain the functions of organelles by playing a game matching up the function and location of each organelle in episode 4. Students will also make connections between what type of cell the organelle is found in and how it aids in the function of that cell type.

 

Students will elaborate on their understanding of organelle function in episode 5 by writing a story that illustrates what happens to a cell if one of its organelles is no longer able to function.


In the final assessment, the students will be evaluated on their understanding of the functions of organelles and how those functions allow a cell to survive.

Conceptual Understandings

Living things must perform life functions such as eating, getting rid of wastes, and breathing

How do living cells perform the functions they need to do to survive?

Snapshot

Students will brainstorm the functions that living things must perform in order to survive.

Episode 1

Question

What are characteristics of living things?

 

Episode 2

Question

How do living cells perform the functions they need to do to survive?

Snapshot

Students investigate the roles of the organelles that are found in the cells of living things.

Conceptual Understandings

Cells have parts such as chloroplasts and cell membranes that perform functions that allow the cell to survive.

How do the organelles help the cell to survive? Can we observe specific ways the organelles function?

 

Conceptual Understandings

Cell membranes allow water in and out of the cell by the process of osmosis.

Do I understand the functions of the organelles?

Snapshot

Students will conduct a lab investigating how cell membranes allow water in and out of a cell.

Episode 3

Question

How do organelles help the cell to survive? Can we observe specific ways the organelles function?

Episode 4

Question

Do I understand the functions of the organelles?

Snapshot

Students will play a game to check their knowledge of the organelles and their functions.

Conceptual Understandings

Cells have parts such as chloroplasts and cell membranes that perform functions that allow the cell to survive.

What happens to a cell when its organelles don’t function properly?

 
 

Conceptual Understandings

Organelles perform important functions and would affect the cell if they were missing.

Snapshot

Students will figure out what will happen to a cell if it is missing one of the organelles they have researched.

Episode 5

Question

What happens to a cell when its organelles don’t function properly?
